Big Tech carries Wall Street to the close of its winning, roller-coaster week

Big Tech stocks carried Wall Street Friday to the close of a winning, roller-coaster week, one that saw markets swing from fear to relief and back to caution because of President Donald Trump's trade war.

The S&P 500 rose 0.7% to add some more to a big three-day rally, and it's back within 10.1% of its record set earlier this year. Spurts for Nvidia and other influential tech stocks sent the Nasdaq composite up a market-leading 1.3%.

But they masked a mixed day of trading on Wall Street, where more stocks fell within the S&P 500 than rose, and the Dow Jones Industrial Average added only a modest 20 points, or 0.1%.

Alphabet climbed 1.7% in its first trading after Google's parent company reported late Thursday that its profit soared 50% in the beginning of 2025 from a year earlier, more than analysts expected.

Alphabet is one of the biggest companies on Wall Street in terms of size, and that gives its stock's movements extra influence on the S&P 500 and other indexes. Another market heavyweight, Nvidia, was also a major force pushing the S&P 500 index upward after the chip company rose 4.3%.

They helped offset a 6.7% drop for Intel, which fell even though its results for the beginning of the year also topped expectations. The chip company said it's seeing "elevated uncertainty across the industry" and gave a forecast for upcoming revenue and profit that fell short of analysts’ expectations.
